A framework for discovering non-obvious product solutions by rapidly building and testing radical, opposing versions of a feature's core attributes. Use this when stuck between mediocre design options, when a feature involves a fundamental trade-off (like speed vs. safety), or when designing a V1 from scratch.

From the source SKILL.md

This framework avoids the "trap of the middle ground" by forcing teams to explore the radical ends of a design spectrum. By building "extreme" versions of a feature, you reveal hidden requirements and emotional hooks that lead to an "obvious in hindsight" solution.
